Hello, Is a kernel called the "boundary" kernel available for kernel density plots? In the help, I can only see the following kernels: "gaussian", "rectangular", "triangular", "epanechnikov", "biweight", "cosine" or "optcosine". The boundary kernel apparently improves the estimate in a neighborhood of zero.
